FrederickTrogisio was a councillor of King Robert of Naples, [1] who served as bailli of the Principality of Achaea from July 1318 until 1321. [2] [3]
His appointment marks the start of a series of foreign governors being appointed over the Principality. [4] His tenure was troubled, both domestically, as Angevin control over the Principality was contested, [5] as well as due to the threat posed by the Catalan Company, that had recently conquered the neighbouring Duchy of Athens. [6] Most notably, the same period saw the expansion of the Byzantine province of Mystras: the bailli and his army were heavily defeated at the Battle of Saint George in September 1320 by the Byzantine sunder Andronikos Asen, leaving the centrally located province of Arcadia in Byzantine hands.

The Principality of Achaea or Principality of Morea was one of the vassal states of the Latin Empire, which replaced the Byzantine Empire after the capture of Constantinople during the Fourth Crusade. It became a vassal of the Kingdom of Thessalonica, along with the Duchy of Athens, until Thessalonica was captured by Theodore, the despot of Epirus, in 1224. After this, Achaea became for a while the dominant power in Greece.

The archbishops maintained close relations with the Republic of Venice, which governed the barony in 1408–1413 and 1418. The barony survived until the Byzantine reconquest in 1429–30.

After Veligosti was lost to the Byzantines towards 1300, the name was retained even though the barony was reduced to Damala.

Charles, and many of his successors, ruled the principality through their baillis, and never visited it in person. Originally, the baillis were Angevin officials, but the post was often given to powerful feudatories from Achaea and the rest of Frankish Greece.
